My first time incubating eggs with my grandkid. One of the eggs was breaking open and you could hear the chick chirping. Well my 3 yr old granddaughter knocked the incubator on to the floor. One successful hatch. The rest are cracked but moving. If I don’t get anymore hatches do I need to purchase a few chicks from the farm store or can I raise this one by itself and put it with m other chickens when it’s ready.
